Was running the CQ WPX CW contest here on 20 meters after a normal transmit
cycle, the radio unkeyed and immediately everything was very quiet. All of
the signals dropped in strength by about 7 S Units.
I tried keying up again but this time I wasn't getting any power out and a
high current

Tony,
Yes I am aware of Softrock and LP-Pan, as well as a whole slew of other
SDRs you could use with the K3's Buffered IF Output.
I suppose the thing I'm trying to get at is a direct I/Q line from the
K3
(on the back of the K3) or not.

Just realized that I keep referring to the amplifier as the KPA100 which
was for the K2.
This problem is pertaining to the K3 and the KPA3 (100W).
Sorry for any confusion I may have caused

I must have spent at least 10 minutes trying to figure that one out.

Leigh,
It's called horrible CW character spacing. ;o)
Terry, W0FM
circuit is ramping up to a voltage every 270 msec
sufficient to cause something to arc over, which is heard as a tic plus
squeal.
It might be worth looking inside your K3 in a dark room.

However, I was able to record the sound using my iPhone.
I have uploaded the audio file here:
